 " MoUusques, decrites par A. Valenciennes," pp. 217-339. Several of the 

 shells are from the East Indies ; and of those assigned to Acapulco, many- 

 appear to have crossed the Pacific by the agency of man. The list of Aca- 

 pulco shells, however, as it appears, is as follows :—

Tellina petalum, Val. Acapulco. Almost exactly like T. solidula. 

 4. Donax radiata, Val. Pacific shores of equatorial America. 



This appears to be either D. punctatostriatus, Hani, var., or 



D. Conradi, Desh., probably the latter; but the description 



is not sufficiently accurate to claim priority. 

 Venus succincta, Val. Acapulco. Probably = Anomalocardia 



subimbricata. Sow. or V. neglecta, Gray. 

 Anodonta glaiica, Val. Acapulco. Appears exactly to accord 



with Anodon ciconia, Gould, except that it is said to be white 



within. Perhaps desciibed from a single specimen. 

 Bulimus undatus. Lam. Mexico. =.Orthulicus zebra, Miill. 

 BuUmus Mexicanus, Lam. Mexico. The shell described in B. M. 



Maz. Cat. p. 177- no. 234, may be the young of this species. 

 Haliotis Californiana, Val. California. 



Turbo peUis-serpentis, [quasi] Val. Acapulco. = Te^fwZa p., Mawe. 

 Nerita textilis, Linn., Lam. Acapulco. 

 Nerita papilionacea, Val. Acapulco. Differs from the last in 



having fewer ribs, and granulations on the lip. Lat. '83. 

 Turritella gonostoma, Val. Acapulco, [Jun.]. 

 Turritella leucostoma, Val. Acapulco. 

 Cerithium musica, Val. Acapulco. Described from one sp. long. 



1 "25 : said to resemble C. literatum, Brug. (not Born and Gualt.). 

 Cerithium granosum, Val. Aca]julco. Probably a Cerithidea. 

 Cerithium stercus-muscarum, Val.* Acapulco. 

 Cerithium fragaria, Val.* " One sp. fished at Acapulco," plaited 



like Fasciolaria, resembles C. lima, long. 1" + . Comp. Fer^a^ws 



gemmatus, Hds. jun.

but ])robably a distinct sjjecies, as it is described " callo sub- 



diviso." 



* These species are not noticed by Sow. jun. in his recent Monograph. His '^ C. granosum, 

 Kien." is an Australian species, like C. corallium; and his " C. musicum, noh." is like C. vulga- 

 tum, but from the Cape de Verd Islands. 



t C. Huviioldti, Val. = C, Pacificum, Sow. teste Jay.
